Chevy Silverado: Stall-No Start P0335 CKP-Part 1

[@jackjohnson9989]

These videos are priceless but man, the backdrop! Neat fences on either side of the driveway, tidy little cabins(?), pastures on either side, animals grazing contentedly in the distance - Oh, the life!

[@Kevinsrack]

Hi Ivan, as always, love the video! My 2008 Pontiac G8 just suffered a similar issue with the CPS. To answer why the sensor's output performs the way it does - the hall effect sensor has what's called a "totem pole" output stage. What this means is, on its output, there are two MOSFETs (but we can think of them like switches), one on top of the other. The top MOSFET is connected to +12v, and the bottom MOSFET is connected to ground. In the presence of the magnetic field, the top MOSFET (or "high side switch") switches on, providing 12v to the output of the sensor. When the magnetic field dissipates, the top MOSFET switches off, and the bottom MOSFET (or "low side switch") switches on, pulling the sensor's output to ground. What probably happens when these sensors start to fail is one of two things. Either A) The high side MOSFET does not turn all the way off and continues sourcing or "leaking" current (more likely), even though the bottom MOSFET is on, or B) The low side MOSFET does not turn all the way on and cannot pull current far enough to ground (less likely). Would love to visit you in PA sometime and shoot the breeze, I'm an electronics engineer with an interest in automobiles, so I'd be happy to teach you things, much like you've taught me thanks to youtube.

[@michaelherbert8213]

Great video. A database for known good waveforms is priceless.

[@SteveRobReviews]

Nice Ivan, I always enjoy to hear your thought process as you take us along for the repair . Look forward to part two 👍

[@help797]

Had no idea of what you've been teaching, fascinating, Thank You

[@bratface90210]

so I've watching everyone of your videos now... you got yourself a subscriber

[@dreamer2355]

I really enjoy your great videos! I feel privileged to be apart of your channel. Your videos are also helping me grow as a tech in this field.

[@PineHollowAutoDiagnostics]

+dreamer2355 Thanks man! It's an awesome field for sure; the learning never stops, especially if you work on several car lines. And the internet is an amazing way to share all the knowledge...that's how I got here too!

[@PineHollowAutoDiagnostics]

Hey James, I'm near the Fairbrook area, about 10 minutes from town. Do you have a vehicle that needs a diagnosis?

[@blackwell1384]

I had a 2002 Chevy Tahoe with a 5.3 that I towed a 7000lb trailer with. When towing I would get a flashing cel every few miles with no perceptible misfire or any other symptoms. It showed misfire codes with misfires on both banks. The shop I took it to threw parts at it with no success. What fixed it, with help from the etcg forum, was a crankshaft position sensor relearn. This worked like a charm and it never set another cel the rest of the time I owned it. We kept the original sensor. I am sure they didn't even check it.

[@PineHollowAutoDiagnostics]

+Jeff Blackwell Yup have seen this before. Maybe the timing chain stretches ever so slightly and causes the false misfires...nice job!

[@atomicdmt8763]

thanks! i recently put in a NEW (but bad) CKP sensor and its apparently shorted internally- screwing up my fuel level gauge, ignition coil/ignitor(?) and setting off a host of other selonoids- et al! I cleaned all grounds, rebuilt my fuse box, new ECU, cleaned everything........no changes UNTIL i just now decided to swap back in the old CKP sensor. All the electrical clicking, etc went away immediately and Im not going thru the KEY RELEARN process for the new ECU

[@ozzstars_cars]

good video. you had me fooled for a minute the crank sensor was ground side switched. now we now its power side switched

[@PineHollowAutoDiagnostics]

+Ozzstar lol I had myself fooled too! Definitely learned that even a simple task like back-probing a connector isn't idiot-proof. The bypass test really saved the day here huh?

[@dcrickerson9775]

Very interesting. Looking forward to part two.

[@stuzman52]

Good stuff Ivan...looking forward to part 2...

[@philh9238]

for the price that scanner is great. no keys to mess with like snaap on. ability to write vins in chrsyslers honda pcms. program ford keys. it gives the verus a good run.

[@kimmat40]

Hey like your vid did it start right up after installing the crank position sensor having the same problem on my 02 avalanche driving for a while then shuts off put a new one in giving a hard time to start put the old one back and started right up that’s the AC Delco made in China unit that u used please let me know thanks

[@rainbowdiamonds2865]

Dir und Deiner Familie ein gesegnetes Weihnachten und ein guten rutsch ins neue Jahr 2020, vor allem aber Gesundheit.

[@diamondstateautodiagnostic5250]

can't wait for part two

[@SmudgyContent]

How can I get mine to relearn the Crankshaft sensor? I have only a cheap scan tool

[@iwinzeazy]

my truck was stalling and giving crankshaft code and it did this for a week until my mechanic found a short in my negative battery cable that was just throwing out codes even after cam and crank sensors were replace....anytime i tried to get up over 40 it tried to shut down the rpm needle was going crazy......hope this helps someone

[@PineHollowAutoDiagnostics]

Please define a short in a ground cable. Was it just a poor connection or a bad corroded wire? A ground cable can't really short to ground ;)

[@iwinzeazy]

bad battery generator control module attached to negative battery cable

[@PineHollowAutoDiagnostics]

What the heck is a battery generator control module?? Like a current meter?

[@dillonkoch72]

I think hes talking about a fusable link ? ANL fuse ?

[@GRowe1978]

Hey Ivan, is that the new Autel scan tool that just came out recently? One of the guys from the parts store said he was going to drop one off to see how we liked it. I was just curious if that's the one he's talking about and if you have an opinion on it? Good, bad, whatever?

[@PineHollowAutoDiagnostics]

+GRowe1978 Nah this is the old trusty Autel MaxiDas DS708. Highly recommended for broad OEM-specific coverage. Just don't get your hopes up to do anything on OBDI cars or graph/save the data lol

[@GRowe1978]

motoYam82 Have you used the new one? I'm not familiar with them at all. The parts store is raving about it, but I have my doubts. LOL!

[@whitetiger8652]

Great video Ivan.

[@Pablo_Automotive]

Great video i am waiting for the part 2 =)

[@garysmith9772]

I have that same "Owan" 120 volt/ battery powered scope. Could you please do a video on general automotive electrical testing with that scope . I dont have the money for any real snap-on scope and would really appreciate, I'am still learning but afraid to damage this scope using it wrong. Please help.

[@PineHollowAutoDiagnostics]

+gary smith Hi Gary, absolutely! I am planning a series of videos on using an oscilloscope, including all the accessories that can be useful in automotive diagnostics. We can definitely do a Verus vs. Owon vs. Pico comparison :) I have also made my own pressure transducer from scratch, so that will be interesting to experiment with...

[@garysmith9772]

That with be great cannot wait. I rate your videos as some of the most informitive in the auto electrical catagory.

[@PineHollowAutoDiagnostics]

PDS5022T and SDS6032V 2-channel scopes with optional battery packs. SDS is a great tool, but surprisingly lacks the ability to save waveforms in full detail. These are collecting dust since the Verus took over :)

[@robertbrandywine]

That's the issue you helped Eric O. with right? Not dropping all the way to zero.

[@RubenKelevra]

Missfires, overheating and stalls... 🤔 Must be the fuel pump! 😌 Wondering what some mechanics do for living 🙄

[@dbus14x]

Awesome , Thanks I learn alot today .

[@conjuntomontemayor93215]

hi i have a 2003 chevy silverado i did a whole new engine rebuild on the original 5.3 block i bored it out when i re installes the motor it starts and it shuts off... the code i get is a p1518 ive been stuck on it for two years and no mechanic locally herw can figure it out.. can u help

[@whoisfluffy3476]

conjunto montemayor it’s a throttle actuator control module performance code from what I found

[@jameskarl8908]

Where are you in state college???

[@cardoc2477]

They also calling it a ZERO speed sensor, that used to be used on a WSS.

[@federicomontelongo4989]

drive it up!

[@bullnpcola]

1500 hd not that rare but the 4 wheel steering was . I have one can’t bare to part with it.

[@rexanderson5458]

What about a Gopro?

[@martinarrieta7779]

esperamos el otro video

[@clydecalamity6520]

For the love of fuck, save yourself the trouble I went through and take off the o-ring on the old crankshaft sensor and put it on the new sensor. I spent forever trying to smash the new sensor in the hole before I realized the o-ring on it was fucking huge.

[@budaiadi8185]

nice video bro ;)))

[@bigdaddyvu]

Nice quadrasteer

[@sheerwillsurvival2064]

👍🏻👊🏻

[@jasonreynolds9753]

so the check engine light said the crank sensor was bad well then put a. $20 sensor in it don't need a $1000 scanner for that

[@Jengoboys603]

Love the gloves using a scam tool

[@bizzy423]

somebody should invent wifi probes get rid of wires completely..

[@DJDevon3]

Gotta get into editing man. Title the intro with the vehicle you are working on with a text overlay. Cut out a lot of the gibberish and give the viewer the most important points. Did a better job of cutting down the screen glare too. Lots of things you could improve on. Invest in a tripod and gorilla pod. Shaky cam gets a little nauseating to watch after a while. The more you can improve your video quality and editing the more subscribers you'll get I guarantee it.

[@renewedautodiagnostics6525]

I second that

[@PineHollowAutoDiagnostics]

+DJDevon3 Thanks for the suggestions, DJ! What video editing software do you use? Obviously the KZbin editor is kinda primitive. I agree this wasn't the smoothest video...was kind of tired after a 100-mile MTB race over the weekend lol. Also the poor scope connection at the PCM had me chasing a ghost. Part 2 should be short and sweet :)

[@ozzstars_cars]

+motoYam82 I'm not sure if you know about youtube editor has a 'stabilize' feature. It can also be found in the 'enhancement' tab under edit. It will remove a lot of the shakeness. It works well and I use it anytime I film just holding the camera in my hand. Ytube editor might not be the best software but it works well and is FREE! Take it easy- Ozz

[@anti0918]

+Ozzstar The stabilize feature in KZbin is terrible. Never turn that thing on. It distorts the video and puts black shaky bars all around the edges.

[@ozzstars_cars]

I disagree, it works fine for low budget videos that have some shake. Also the stabilizing feature can be adjusted for the amount of stabilization. Use scale 1-3 and its fine. No need to spend lot$ of money for software. I know I make videos. Its the content that is important! Anti please post some of the videos you use with the stabilization features so you can sell me on the idea of spending lot$ of money. I'll post my honest unbiased judgement.
